I can't upload a course from garmin connect to my forerunner 205. I tried it on several computers (windows 8.1), but it doesn't work. When I start to sent the file to my watch (which is recognized by Garmin) I'll get the message: synchronisation failure with Garmin Connect. I tried this with IE11, Chrome and Firefox, but they all don't work. In the past I did this on GPSies, but the Garmin plugin doesn't work anymore.
Has anyone maybe a solution for this problem.
